But how would they obtain cryptocurrency in first place? Using exchange is obviously impossible, while ATM is only available on very few places.
Localbitcoins, Paxful, online deals, exchange for gift cards, if you're not living in a small village in a 3rd world country it's pretty easy to get,
and remember those are gamers, kids who usually have more than 10$ monthly allowance. It has become pretty easy to get cryptos nowadays.

Exactly. In Western countries, $30-$40 per week for a teenager is not something unheard of. Then they buy BTC with cash from their older friends, and voila! - they can place bets.
~I'm also pretty sure there are a lot of people who are only betting with cryptocurrencies and not only they don't touch at all traditional fiat systems but also never had bet previously.
You almost literally described my situation!
It's not that I never had bet previously, but I started doing it hundred times more frequently with crypto. And I just realized that although my crypto bets are usually very small, all of them combined might amount to a number that would be many times higher than what I've wagered in fiat during my whole life.
I think all of us, crypto gamblers, should consider the words said by @gentlemand here:
~How you can favour retaining the currency that's only going to reduce your spending power and piss away the one that may ensure your future is beyond me.

Indeed, it seems more easy to part with crypto than with fiat, but it is so wrong.
